length GMC YUKON XL DENALI 2007 Owners Manual

Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:Using a tool to force the key from
the ignition switch could cause damage
or break the key. Use the correct key and turn
the key only with your hand. Make sure the
key is all the way in. If it is, turn the steering
wheel left and right while you turn the key
hard. If none of this works, then your vehicle
needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Notice:Lengthy operation of features such as
the radio in the accessory ignition position
and the RUN position may drain the battery and
prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine
starts, and you release the key.
D (START):This position starts the engine.

Automatic Operation
AUTO (Automatic):When automatic operation
is active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current temperature(s)
and AUTO will be lit on the display. The current
delivery mode and fan speed will also be
displayed for approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to
help quickly cool down your vehicle. The light
on the button will illuminate in recirculation.2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Use the
driver’s or passenger’s temperature buttons to
adjust the temperature setting as necessary.
If you choose the temperature setting of 60°F
(15°C), the system will remain at the maximum
cooling setting. If you choose the temperature
setting of 90°F (32°C), the system will remain at
the maximum heat setting.Choosing either
maximum setting will not cause the vehicle to
heat or cool any faster.
Be careful not to cover the solar sensor located
on the top of the instrument panel near the
windshield. This sensor regulates air temperature
based on sun load and also turns on your
headlamps. For more information on the solar
sensor, see “Sensors” later in this section.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air
is available. The length of delay depends on
the engine coolant temperature. Pressing the fan
switch will override this delay and change the
fan to a selected speed.

Avoid subfolders. The system can support up
to 8 subfolders deep, however, keep the total
number of folders to a minimum in order to
reduce the complexity and confusion in trying
to locate a particular folder during playback.
Make sure playlists have a .m3u or .wpl
extension (other le extensions may not work).
Minimize the length of the le, folderfolder, or
playlist names. Long le, folder, or playlist
names, or a combination of a large number of
les and folders, or playlists may cause the
player to be unable to play up to the maximum
number of les, folders, playlists, or sessions.
If you wish to play a large number of les,
folders, playlists or sessions, minimize
the length of the le, folder, or playlist name.
Long names also take up more space on
the display, potentially getting cut off.
Finalize the audio disc before you burn it.
Trying to add music to an existing disc
may cause the disc not to function in the
player.You can change playlists by using the previous
and next folder buttons, the tuner knob, or
the seek buttons. You can also play an MP3
CD-R that was recorded using no le folders.
If a CD-R contains more than the maximum of
50 folders, 50 playlists, and 255 les, the player
will let you access and navigate up to the
maximum, but all items over the maximum will
not be accessible.
Root Directory
The root directory of the CD-R is treated as a
folder. If the root directory has compressed audio
les, the directory will be displayed as the CD
label. All les contained directly under the
root directory will be accessed prior to any root
directory folders. However, playlists (Px) will
always be accessed before root folders or les.
If a disc contains both uncompressed CD
audio (.CDA) and MP3 les, a folder under the
root directory called CD will access all of the
CD audio tracks on the disc.
287

Minimize the length of the le, folder or playlist
names. Long le, folder, or playlist names, or a
combination of a large number of les and
folders, or playlists may cause the player to be
unable to play up to the maximum number of
les, folders, playlists, or sessions. If you wish
to play a large number of les, folders, playlists,
or sessions, minimize the length of the le,
folder or playlist name. Long names also take
up more space on the display, potentially
getting cut off.
Finalize the audio disc before you burn it.
Trying to add music to an existing disc may
cause the disc not to function in the player.
Root Directory
The root directory of the CD-R is treated as a
folder. If the root directory has compressed audio
les, the directory will be displayed as F1
ROOT. All les contained directly under the root
directory will be accessed prior to any root
directory folders. However, playlists (Px) will
always be accessed before root folders or les.
Empty Directory or Folder
If a root directory or a folder exists somewhere
in the le structure that contains only folders/
subfolders and no compressed les directly
beneath them, the player will advance to the
next folder in the le structure that contains
compressed audio les and the empty folder will
not be displayed or numbered.
No Folder
When the CD-R contains only compressed les,
the les will be located under the root folder.
The next and previous folder functions will not be
displayed on a CD-R that was recorded without
folders or playlists. When displaying the name of
the folder the radio will display ROOT.
When the CD-R contains only playlists and
compressed audio les, but no folders, all les
will be located under the root folder. The
folder down and the folder up buttons will search
playlists (Px) rst and then go to the root
folder. When the radio displays the name of the
folder the radio will display ROOT.

Drunken Driving
Death and injury associated with drinking and
driving is a national tragedy. It is the number one
contributor to the highway death toll, claiming
thousands of victims every year.
Alcohol affects four things that anyone needs to
drive a vehicle:
Judgment
Muscular Coordination
Vision
Attentiveness
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most
cases, these deaths are the result of someone who
was drinking and driving. In recent years, more
than 16,000 annual motor vehicle-related deaths
have been associated with the use of alcohol, with
more than 300,000 people injured.Many adults — by some estimates, nearly half the
adult population — choose never to drink
alcohol, so they never drive after drinking. For
persons under 21, it is against the law in
every U.S. state to drink alcohol. There are good
medical, psychological, and developmental
reasons for these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink
alcohol and then drive. But what if people do?
How much is “too much” if someone plans
to drive? It is a lot less than many might think.
Although it depends on each person and situation,
here is some general information on the problem.
The Blood Alcohol Concentration (BAC) of
someone who is drinking depends upon
four things:
The amount of alcohol consumed
The drinker’s body weight
The amount of food that is consumed before
and during drinking
The length of time it has taken the drinker to
consume the alcohol

Q:Am I likely to stall when going downhill?
A:It is much more likely to happen going
uphill. But if it happens going downhill, here is
what to do.
1. Stop your vehicle by applying the regular
brakes. Apply the parking brake.
2. Shift to PARK (P) and, while still braking,
restart the engine.
3. Shift back to a low gear, release the parking
brake, and drive straight down.
4. If the engine will not start, get out and
get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go
across the incline of a hill. If this happens,
you have to decide whether to try to drive across
the incline. Here are some things to consider:
A hill that can be driven straight up or
down may be too steep to drive across. When
you go straight up or down a hill, the length
of the wheel base — the distance from
the front wheels to the rear wheels — reduces
the likelihood the vehicle will tumble end
over end. But when you drive across
an incline, the much more narrow track
width — the distance between the left and
right wheels — may not prevent the vehicle
from tilting and rolling over. Also, driving
across an incline puts more weight on
the downhill wheels. This could cause a
downhill slide or a rollover.
Surface conditions can be a problem when
you drive across a hill. Loose gravel, muddy
spots, or even wet grass can cause your tires
to slip sideways, downhill. If the vehicle
slips sideways, it can hit something that will
trip it — a rock, a rut, etc. — and roll over.
